基站已被认为是当前移动网络中最耗电的部分。由于它们的功率分布只取决于实际业务负载的一小部分，因此将一些基站置于休眠模式被确定为一种根据实际负载来调整网络功耗的解决方案。本文提出了一种新的基于“细胞随需应变”模式的系统架构，该架构目前正被GreenTouch联盟的Beyond Ccell Green Generation(BCG2)项目所研究。我们首先概述了新系统体系结构的主要特征，然后提出了一个位置信息处理框架，以预测用户和一组可能被系统激活以服务于用户的关闭的基站之间的信道质量。在小规模试验台上的实验评估表明，该框架的估计误差为20%。
Base stations have been identified to be the most power consuming part in current mobile networks. Since their power profile only depends to a small fraction on the actual traffic load, putting some base stations in sleep mode has been identified as a solution to scale the network power consumption with the actual load. This paper presents a new system architecture based on the paradigm of “cell on-demand”, which is currently studied in the Beyond Cellular Green Generation (BCG2) project of the GreenTouch consortium. We first outline the key characteristics of the new system architecture, then, we present a framework for position information processing in order to predict the channel quality between a user and a set of switched-off base stations that can potentially be activated by the system to serve the user. Experimental evaluation on a small scale testbed shows the viability of the proposed framework by achieving estimation errors of 20%.
